When writing a letter to an unknown recipient, instead of using "Sir or Madam," another option is to use "To Whom It May Concern." The preferred capitalization rule is to capitalize all of the words in that phrase. Even though the salutation is generic, the letter should follow standard business rules.
Begin the letter with the address details of the sender as well as the recipient. Also include the date. The letter should be written on company letterhead, if applicable.
When writing a letter to an unknown recipient, it is helpful to include a reference line. This is usually noted in "Re:" format and is a short statement of the purpose of the letter. For example, "Re: Reference for Ms. Jane Doe."
In the first paragraph, the person writing the letter should introduce him or herself. Explain the reason for the letter so the recipient knows what to expect.
Include details and any other information that might be helpful to the recipient. In a reference letter, for example, describe the person and how he or she would benefit the company.
Thank the reader for his or her time. Be sure to leave contact information such as an email or cell phone number.
